Subject: [PATCH 1/2] bump VTK to OSPRay 3 API

Change CMake script to look for 3.
Stop using previously deprecated OSPRay APIs, they are removed in 3.0.
Use new parameter signatures including:
  uint for enums
  box1f instead of vec2f for ranges
  "valueRanges" TransferFunction parameter is now "value".
  linear2d for texture transforms
ospNewMaterial no longer accepts renderertype first argument
Implicit isocontours now take their appearance settings from
  GeometricModel instead of VolumetricModel.
